Piping Elbow

Manufacturer

To make a change in the flowing direction of any material, we use Piping Elbow. Elbow helps in losing pressure to the plant system due to friction, re-acceleration, and impacts. When any products enter inside the elbow, it starts moving straight towards the outlet of the elbow. Various categories such as elbow design, products characteristics, conveying velocity and specific load or the product-to-gas ratio helps determine deflection angle by elbow design. Furthermore, the products usually hit one or more subordinate force areas before it exits the elbow.
Usually, of 90 degrees or 45-degree angle, piping elbow is a joint in two lengths of pipes leading to change in direction. On other hand, Fittingcart makes 22.5-degree piping elbows with machined ends for usage in butt welding, threaded (generally female), etc. “Piping” denotes its use in high-pressure areas, high temperature, flow or unpredictable materials.

To define distance upon which they change direction, Piping elbows are of two types as Long Radius and Short Radius. The center line of one end to opposite face is “center of face” distance and ironically, is equal to radius through which elbow is bent. The LR (long radius) has a center to face distance at 1½ x Nominal Pipe Size (NPS) (1½D)”, whereas “short radius” is even to nominal pipe size.

MATERIAL SPECIFICATION

ASME B16.9.

defines the dimensional tolerances etc. for long and short radius elbows

Types of Piping Elbow

90-Degree Piping Elbows: Also, “90 bends or 90 ells” is a piping elbow bent to change in direction of flow in angle at 90 degrees. In other words, it is “quarter bend”. Moreover, 90-degree elbows tend to joint quickly when you connect it to copper, plastic, steel, cast iron or lead materials. Still, you can also attach the piping elbow to rubber using stainless steel clamps. Of course, Fittingcart offers piping elbows in various materials such as silicon, galvanized steel, rubber compounds, NPT Thread and nylon, etc. 90-degree piping elbows are commonly used to link hose to valves, deck drains and water pressure pumps.

45 Degree Piping Elbow: Another name of 45-degree piping elbow is “45 bends or 45 ells”. They are generally linked to pipes at a 45° pipe angle only. Similar to 90-degree elbow, 45-degree piping elbow tends to change flow direction to 45 degrees and gets connected to copper, plastic, lead, steel, rubber, etc. Meanwhile, Fittingcart produces piping elbows in various sizes, in male to female BSP Thread connections that in many color ranges. In first place, their use is in water supply faculties, chemical, and food industrial pipeline networks, garden, and agriculture transport systems, solar energy pipelines, etc.

A Brief to Bends and Elbows

Pipe Bends Elbow: There is huge confusion with terms bend or elbows being same and often use them as synonyms. In my opinion, the bend is the biological term for modifications in the flow direction in pipings. On other hand, elbows is an engineering thing with its classification into 90 degrees or 45 degree and short or long radius. Moreover, elbows have standard levels and size bend limits.Production of bends is as per demands of piping whereas elbows are already outputs and cannot be off the shelf. The radius of curvature is the main difference point as elbows have radius of curvature within one to twice the diameter of the pipe. While Bends have a radius of curvature more than twice the diameter.Elbows have sharp corners which lack in bends. In addition, bends have less pipe friction and the flow is smoother while welding makes friction in elbows. All bends are not elbows but all elbows are bends.

Applications of Piping Elbow

Made of heavy and strong materials for usage in tough areas of severe high/low-temperature resistance etc.

Main purpose is to use on process systems, instrumentation, and ingredients used in chemical, fluid power, electronic and pulp-paper plants.

Ells alter the direction of a pipe which is useful in various principles like pneumatic and hydraulics depending on final use.

Miter Bends

By the same token, there exists another bend type known as Miter bend. A Miter bend can be made by cutting pipe ends and joining them at an angle. A real miter bend is of 90 degree which is a bend of two pipes at 45 degrees each and is akin by welding. Similarly, if you want to get 90-degree miter bend with three pipe cuts, you need each with 22.5 degrees.

Wall Thickness OF Pipe Elbows

The inside of a radius is the weakest point of an elbow. Only the center to face dimensions and “squareness” dimensional patience match the standards by ASME B16.9. The wall thickness is up to the standard at just the weld line location and not to rest of elbow. According to the standards, the minimum tolerance or patience should lie in 12.5% of the minimum wall thickness. Only the ends of end fittings have maximum thickness.

Preserve your Pipe Elbows

Subordinate forces can be dangerous as they may degrade or break sensitive products, hence leading to dust and dirt.

Heat conscious products like plastic pellets can over heat surface leading to unwanted tails or streamers on pellet and product destruction.
